REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 593,021, dated November 2, 1897.

Application ledJune I2, 1896. Serial No. 595,267. (No model.) l

To @ZZ whom, it may concern.'

Be it known that I, JOHN HYDE, Jr., a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Refrigerators; and I do declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in refrigerators in which a movable elevator controlled and actuated by water from the streetmain occupies a portion of the refrigeratorbody and can at will be raised and lowered, so as to operate between the refrigerator and the room directly above it; and myinvention consists in the arrangement and combination of parts that will be more fully described hereinafter.

Figure lis a vertical section through the refrigerator; Fig. 2, a detail of the elevator, showing my improved method of stopping the same at the required height; Figs. 3 and 4, an elevation and cross-section of my filter; Fig.

5, a vertical section of the refrigerator through the line pp of Fig. l; and Fig. 6, a view of the top of the elevator, showing the entrance of the outdoor air.v

The various parts of my invention are represented by the same figures throughout the various views.

In Fig. l, l is the cross-section of the body proper of the refrigerator, which is placed preferably in the cellar immediately under the dining-room or pantry, where the food can be most conveniently reached.

2 is the elevator, containing shelves for the accommodation of food, as shown.

3 is the fioor of the dining-room or pantry, to which the food is conveyed by the elevator.

4 is a shaft or draftway leading from the upper portion of the refrigerator to the open air through the side of the house.

5 is a similar draft from out of doors a little larger in cross-section than 4, communicating with the lower part of the refrigerator by means of the dampers 6 and 34.

The elevator 2 is actuated by the plunger 7, which is fitted to an outer tube S, the whole being incased in the metallic casing 10, the space between 8 and l() being filled with cement or some equivalent substance in the manner and for the purpose to be hereinafter described.

In practice the plunger need not exceed seven-eighths ofan inch or at the outside an inch in diameter for use in a refrigerator large enough for the needs of a large family.

In addition to the ordinarynon-conducting filling of the refrigerator I also use an airspace in the refrigerator-wall for the purpose of keeping the dampness of the interior from reaching the filling.

27 is the ice-chamber and the ice therein resting upon the slatted bottom, as shown, the side slats of said chamber being shown in cross-section at 35. These slats, as will be seen, are beveled in such a manner that the drip of the ice as it melts is thrown toward the center of the ice-receiver without interfering with the escape of the cold air from the ice into other portions of the box.

Immediately below the ice-chamber is the coil of pipes 17 (shown in cross-section in Fig. 5,) through which the drip from the melting ice passes and is finally caught by the pan 36 and passes out through the pipe 28.

l5 is a lilter connected with the water-main 13 through the branch pipe 14 and the valve 19. The water from the main passes' through le into the filter l5 through the same, thence through the pipes 16 into the coil 17, thence by the pipe 18 to the faucet 23 into the dinin g-room above, where the cooled and filtered water may be drawn for use.

The filter l5 is so connected with the pipes which lead to and from it as to be easily removed for the purpose. of cleaning or refilling, comm on easily-removable couplin gs being used for this purpose.

The elevator and plunger are operated by water from the street-main, led to the lower part of the cylinder by the pipe 26. At 2O is a valve operated by a faucet 2l in the room above by which water is admitted to S from the streetmain, and the elevator is thus brought to the room above. Vhen it is desired that the elevator should descend, the valve 2O is closed and the valve 24 is opened IOO by means of the faucet 22. The weight of the elevator then drives the water slowly back through the same pipe 2G and out through the valve 24, this latter being of a size to allow the elevator to return at a suitable speed and through the escape-pipe 25 until the elevator reaches its normal position within th refrigerator.

The drafts 4 and 5 are intended for use in cool weather when it is Vnot necessary to use ice. The draft 4, being connected with the top of the refrigerator, allows the heated air and gases from the food to escape to the outer air, while the draft 5, connected with the lower part of the refrigerator, allows the admission of cooled air from outdoors, thus causing a constant circulation through the refrigerator. These drafts 4 and 5 are entirely within the refrigerator-body, as shown best in Fig. 5, where the dampers 6 and 34 are also shown most clearly. By-means of these danipers the admission of outdoor air can be regulated at will. The best results are obtained by leaving the draft 4 open at all seasons of the year, while 5 is kept closed at all times, except during cold weather.

As is shown in Fig. l, the upper part of the refrigerator has an opening through which the elevator passes, the top of the elevator 2 being larger than the opening, so that it fits down 'flush against the iioor when the elevator is within the refrigerator and the space between the top of the refrigerator is filled in, as shown by the heavy black lines upon each side of the opening. There is also an opening 33 in the bottom of the refrigerator for the purpose of fixing in position the cylinder 10 containing the interior cylinder S and the pipe 26, the opening 38 also serving for the purpose of removing said cylinder IO in case a removal is at any time necessary. After the cylinder is constructed the cylinder l0 is placed in the earth below it, the base 1l located properly, and the inner cylinder 8 placed in position with the plunger 7 contained therein. The cylinder 8 is then adj usted so that the plunger 7 is perfectly upright or perpendicular, andthe pipe 26 is then connected with the base ll, and the stops surrounding S and 26 are lled with cement or some equivalent material, thus making the outer cylinder IO and its entire contents one solid piece, which can be removed or changed in position without disturbing the interior pipe and cylinder. The space about the plunger 7 within the cylinder 8 is very small, the inner diameter of 8 being not more than an eighth of an inch larger than the diameter of the plunger 7, so that an exceedingly small quantity of water serves to operate the elevator.

Fig. 2 is a vertical cross-section of the elevator 2 through the line Qc as and shows the method of stopping the elevator when it has reached a suitable height, and also a means for removing the elevator entirely in case that is necessary.

29 29 in Fig. 2 are two stops fixed one upon each side of the shaft in which the elevator moves, and 30 30 are metallic spring-hooks screwed to the elevator side upon the upper extremity and projecting so as to engage the stops 29 29 when the required height has been reached.

In case the elevator is to be taken entirely out of the refrigerator the lower extremities of 30 30 are sprung away from the stops and the elevator lifted out entirely, leaving the plunger 7 in its cylinder, the whole weight of the elevator when empty not exceeding twenty-five or thirty pounds.

3l in Fig. 2 represents cross-braces for stiffening the projecting lower portion of the elevator,which in turn serve to keep the elevaF tor in place when the greater part of it is above the floor 3.

By means of the construction above described it will be seen that all of the parts of the lifting device, including the supply-pipe 26, are placed in position from the top of the outer casing I0, the parts being placed in position and then secured by means of cement. They can be put together in the shop, and then it is only necessary to bore a hole in the ground and insert them all at once.

Having now described my invention, what I claim, and desire to secure by Letters Patent, isl l. The combination of an elevator, a casin g 10, having an open top, a hydraulic cylinder 8, situated in and of less diameter than the casing, a piston 7 situated within the hydraulic cylinder and connected with the elevator, a chamber ll situated at the bottom of the cylinder,a water-supply pipe extending downward within the casing, and communicating with the chamber Il, and a body of cement surrounding the cylinder,chamber and watersupply pipe, substantially as described.

2. A refrigerator having an opening in its top, and an opening through its bottom, an elevator, and its rod 7 connected to its lower end, combined with a hydraulic cylin der which extends up through the bottom of the refrigerator, a water-supply pipe alongside of the cylinder, the chamber ll forming the lower portion of the cylinder and with which the Water-supply pipe connects, an inclosing case around the cylinder, chamber and water-pipe and a filling of cement between the casing and the cylinder-chamber and water-pipe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
